Trigonometric Ratios of Special Angles

$$\begin{array}{c|c|c|c|c|c}
& 0^\circ & 30^\circ & 45^\circ & 60^\circ & 90^\circ \\ \hline
\rule[-4mm]{0mm}{10mm} \sin \theta & 0 & \dfrac{1}{2} & \dfrac{\sqrt{2}}{2} & \dfrac{\sqrt{3}}{2} & 1 \\ \hline
\rule[-4mm]{0mm}{10mm}\cos\theta & 1 & \dfrac{\sqrt{3}}{2} & \dfrac{\sqrt{2}}{2} & \dfrac{1}{2} & 0 \\ \hline
\rule[-4mm]{0mm}{10mm} \tan\theta & 0 & \dfrac{\sqrt{3}}{3} & 1 & \sqrt{3} & \mbox{undefined}
\end{array}$$
